Nws yog nruab nrab-muaj zog acid nrog cov tshuaj formula H3PO4 thiab molecular hnyav ntawm 97.995. Tsis volatile, tsis yooj yim rau decompose, yuav luag tsis muaj oxidation.
Phosphoric acid feem ntau yog siv rau hauv kev lag luam tshuaj, zaub mov, chiv thiab lwm yam lag luam, suav nrog cov tshuaj tiv thaiv xeb, khoom noj khoom haus, kho hniav thiab orthopedic phais, EDIC caustics, electrolytes, flux, dispersants, industrial caustics, chiv ua raw khoom thiab cov khoom siv tu tsev. , thiab tseem tuaj yeem siv los ua tshuaj lom neeg.
Kev Ua Liaj Ua Teb: Phosphoric acid yog cov khoom siv raw rau kev tsim cov phosphate chiv tseem ceeb (calcium superphosphate, potassium dihydrogen phosphate, thiab lwm yam), thiab tseem siv rau kev tsim cov khoom noj pub mis (calcium dihydrogen phosphate).
Kev lag luam:Phosphoric acid yog ib qho tseem ceeb chemical raw khoom. Nws lub luag haujlwm tseem ceeb yog raws li hauv qab no:
1, kev kho cov hlau nto, tsim ntawm insoluble phosphate zaj duab xis ntawm cov hlau nto, tiv thaiv cov hlau los ntawm corrosion.
2, tov nrog nitric acid raws li ib tug tshuaj txhuam hniav, los txhim kho cov tiav ntawm cov hlau nto.
3, kev tsim cov khoom siv ntxhua khaub ncaws, tshuaj tua kab raw khoom phosphate ester.
4, kev tsim cov khoom siv raw uas muaj phosphorus nplaim retardant.
Khoom noj khoom haus:phosphoric acid yog ib qho ntawm cov khoom noj khoom haus additives, nyob rau hauv cov zaub mov raws li ib tug qaub neeg sawv cev, poov tshuaj noj neeg sawv cev, cola muaj phosphoric acid. Phosphates tseem yog cov khoom noj khoom haus tseem ceeb thiab tuaj yeem siv los ua cov khoom noj ntxiv.
Tshuaj: Phosphoric acid tuaj yeem siv los ua cov tshuaj phosphorous, xws li sodium glycerophosphate.
